NARROW- -WARE LOOM.

SPECIFICATION forming part of Letters Patent No. 704,295, dated July 8,1902.

Application filed July 9, 1900,

To (tZZ whom, it may concern.-

Be it known that 1, JOHN C. BROOKS, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Narrow-Ware Looms,of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to the needle-motion or the mechanism for insertingthe loop of weft or filling in looms used for weaving narrow fabrics;and the invention consists in certain improvements in the constructionof such mechanism, as hereinafter described and claimed.

Figure 1 of the drawings is a view in elevation, partly broken out,showing the manher of mounting upon the baton or lay of a loom thesleeve which carries the weft-inserting needle. Fig. 2 is a plan viewofa section of the baton or lay, showing my improvements applied thereto.

A post 11 passes through an opening a in the baton A and is secured tothe baton by means of screws a. Mounted so as to oscil late freely onthis post is a sleeve 0, having at its lower end a hub 19. The lowerface of this hub and the corresponding part of the baton are providedwith circular grooves for the reception of a ball-bearing 0, whereby aneasy motion of the said sleeve is secured. The said hub 19 is providedat the front thereof with radial pins or projections n. Reciprocatinglongitudinally at the front of the baton is a rack g, which is providedwith upright pins 0', adapted to engage the radial pins n, carried bythe hub 19.

Reciprocation longitudinally of the rackq by any desired means will givean oscillating movement to the sleeve 0. Attached at the upper end ofthe sleeve 0 is an arm e, extending a short distance inward or towardthe rear of the loom. This arm constitutes the needle of the loom and isprovided with devices by means of which the weft-thread is laid in theshed formed in the warps l3. Extending longitudinally of the arm is avertical slot 8, and in this slot is located a take-up and tensiondevice for the weft-thread, such device consisting of an eye 1;, throughwhich the weft Serial No. 23,283. (No model.)

passes in the manner hereinafter described, and a spring it, connectedat one end to the eye 12 and at the other end to the arm or needle cin arecess t, extending from the slot .9 toward the axis of the arm c. Theouter end of the arm or needle 6 is provided with a slot in which ispivoted at h a finger j. A spring Z, attached to the arm or needle 6near its extreme end f, bears upon the finger j beyond the pivotal pointthereof and serves to hold the said finger normally in a positionapproximately parallel to the arm (2. The part c is provided with a ductor guide w, through which is drawn the weft or filling 115 from anysuitable source of supply. The finger j is provided with a correspondingopen ing i. Through the duct w the weft passes, thence through the eye vof the tension device, and out through opening 2' of the finger 7'. Thefilling rests against the outer side of the finger j after passingthrough the eye therein and is by this device properly laid in the shed.

In looms employing needle-motions it is necessary in order to produceperfect fabrics that the loop of thread inserted by the needle be heldat one selvage of the fabric, so as to prevent such loop of thread beingretracted when once laid, and it is customary to use a selvage-shuttleto lock the looped thread at the selvage opposite from the side ofinsertion. Attached to the baton A and in position to be struck by therear end g of the fingerj when the arm or needle is passed through theshed is a stop y. This stop serves to rock the finger j against theforce of the spring Z and by that means widens the space between the twoparts of the weft-thread forming the loop, so as to facilitate thepassage therethrough of the selvage-thread shuttle or other selvagemechanism, (indicated by the letter 0.)

It is obvious that the face of the finger 3' might be provided with alongitudinal groove extending from the eye 2' therein to better guidethe weft-thread as the same is laid in the shed.

Having thus described my invention, what I desire to secure by LettersPatent is 1. In a needle-motion for looms, the combination of anoscillating arm or needle having a weft-tension device, of aweft-delivering'finger pivoted at the end of the said arm engagingdevice, and a spring inclosed within said needle, one end of the springbeing socured to the needle and the other to the threadengaging device.

In testimony whereof I have aflixed my signature, in the presence of twoattesting witnesses, this 15th day of June, 1900.

JOHN C. BROOKS.
